Objective: The study represents a comparative analysis and determination of optimal methods of filing dislocated complexes ‘intraocular lens (IOL) – capsular bag’ in various clinical situations.
Methods: The studies were conducted in a group of 15 patients (15 eyes) with a dislocation of the IOL – capsular bag complex, 2–3 stages. The patients were divided into the following groups: 1) with stapling with an anchor suture to the iris for one haptic element; 2) with stitching with interrupted sutures to the iris for two haptic elements; 3) with transscleral fixation with one suture; 4) with transscleral fixation with two sutures; 5) with transscleral fixation with three sutures.
Results: In one eye with fixation of the IOL – capsular bag complex for two haptic elements to the iris, a rise in intraocular pressure up to 28 mm Hg was observed in a month. In the eye with the HANITA SeeLens IOL, the upper haptic element was dislocated from the fixation suture one day later. In the eye with the HANITA SeeLens IOL with transscleral fixation with three stitches behind the intracapsular ring a week later a lens dislocated inside ‘the capsular bag – intracapsular ring’ complex. Visual acuity in all cases, excluding patients with re-dislocation of the IOL, increased by an average of 0.3. Conlusions: Fixing any number of IOL sutures made of hydrophilic acrylic, except for IOL with various openings and rings in the haptic elements, cannot be considered stable and safe in terms of predicting complications in the early and late postoperative periods. Transscleral technique is the most stable and reliable method for fixing stationed IOLs.
